Merge master 7e2b049d8e2523127a3b4fba38cab4748ef0c72f, observed on 2026-09-19 at 07:38:37 UTC, into release/session-log-v4 at c4663e8671e33bc2cfdbc868b0b18d979508d39b. Keep this base integration separate from the five persistence repair PRs so their review diffs remain focused and can be rebased without moving their fixes here. Combine master's pin ordering and archived-session filter with V4's parent-owned direct child catalog. Both grouped and flat sidebar rows must pass the Session list to the V4 activity calculation; restoring master's summary-lineage traversal would reintroduce the removed subagent ownership and count unrelated descendants. Keep master's removal of the archived-session settings page. Its only release-side test change renamed a Session list fixture field, so no runtime behavior is lost by deleting that obsolete test. Adapt the release-side direct-child-status regression to the new row/filter arguments and preserve its assertions. Retain master's workspace ordering and row-motion documentation while keeping the V4 child-catalog wording. Reconcile the generated bilingual records against the merged documents. Frozen V0-V3 codecs, recorded Session JSONL inputs, and the current V4 persistence schema are unchanged. Refs #2692, #3273
Subsystems
English | 中文
One page per subsystem of the DeepSeek Harness: what it is, the data structures it moves, and — where a ctx service or event scope backs it — a generated Cordis API section carrying its service and event reference. The folder complements architecture.md, which describes behavior across subsystems (the service map, the session/turn/step lifecycle, the event taxonomy); each page here is the reference for one subsystem's vocabulary and wiring.

Type declarations and their JSDoc on these pages are source-equivalent and drift-checked by
pnpm run verify-type-equiv(see development.md). Ordinary blocks preserve complete declarations;public-apiblocks preserve body-stripped public class declarations. Cordis services and events use each page's generated Cordis API section.
